What Are Three Different Changes That You Might Be Required

Question

Examlex · Accepted Answer

The Answer is You might be called on to implement the following three types of changes to existing software:
• patch—A software patch is a correction, improvement, or enhancement to software. It corrects a bug, closes a vulnerability, or adds minor enhancements to only part of the software, leaving most of the code untouched. Microsoft sometimes releases a major group of patches to Windows or a Microsoft application, which it calls a service pack.
• upgrade—A software upgrade is a major change to a software package that enhances the functionality and features of the software, while also correcting bugs and vulnerabilities. When a patch or upgrade is applied to device drivers, it is called a driver update.
• rollback—A software rollback, also called backleveling or downgrading, is the process of reverting to a previous version of software after attempting to patch or upgrade it.
